Model 201LP Two Wire Triboelectric Detector / Broken Bag Detector

The Redkoh Model 201LP is a two wire 4-20mA particulate monitor that measures particulate levels in air ducts on a real time basis.

The Model 201LP is powered by an external 4-20mA loop and can be connected directly to a PLC, recorder, or digital readout. Changes in the 4-20 mA output are directly related to changes in the concentration of particulate in the gas stream.

Applications

Applications for the 201LP monitor include but are definitely not limited to process control, dry solid levels, and environmental applications such as:

Bag house / fabric filter

Truck and rail off-loading

Packaging stations

Feeders

Cyclone separators

Storage silos

Using an array of monitors on bag house compartments and/or outlet ducts is an excellent means of detecting broken bags before an emissions exceedance is reached.

Sensitivity

The Model 201LP system can detect a particulate loading as small as .0005gr/dscf (1mg/m3). There are five selectable sensitivity ranges to cover every requirement.

Broken Bag Detection

The Model 201 LP Broken bag detector is a loop powered device. The 201LP is a cost-effective device for multiple compartment bag house applications. It is sensitive enough to not only detect broken bags, but also to detect the presence of worn bags.

Features

NEMA 4X enclosure

Stainless steel probe lengths are available from 6” to 48” in 6” increments. Custom sizes can be supplied

Standard 2-wire configuration with 4-20 mA output

Single opening to duct via ½” NPT coupling

The Model 201LP monitor uses the Triboelectric principle to measure the electrical charge imparted by dust particles as they strike the probe The charge picked up by the probe is converted to an electrical current, which is measured by the electronic system.
